What you are asking is quite straight forward.
You can put Asterisk (with FXS ports) behind almost any PBX or Key System
All you need are some spare ports on a CO Line card inside you PBX
The FXS card simulates a ringing CO line and you PBX or Key System
doesn't know the difference.
So you configure Asterisk to ring the FXS port as an extension every
time a call comes from one or more
SIP or IAX extensions. These extension can be anywhere Toronto, the UK
or Timbucktoo.
as long as they have internet access its ZERO cost per minute
It would be my guess that your NEC phone system uses propietory phones
and you will have to get your service
company in Calgary to provision the extra incoming lines.
Good luck and save money

the only foggy area remaining is how i can get free ld to Calgary? Our
Calgary office has a NEC NEAX 2000 IPS system which i have been told
uses ip phones, and so i believe their system is ip enabled. My
questions is, how to a setup a connection between the two offices?
I did this with our Norstar MICS before I went to PRI (which makes it much
easier) -- I had a TDM400 with FXS ports and hooked them into a couple of
extra 'trunk' lines on the Norstar.
What I did then was to program the speed dials such that the speed dial to our
sister office picked up a specific set of trunk lines (lines 1-8 were in a
group and connected to Bell, lines 9-12 were in a second group and went to
the TDM card). Asterisk could then take the call and route it to the other
Asterisk box, which was wired the same way.
The Norstar system would simply see a line in the second trunk ring, and it
would do whatever it was programmed to do (in our case, go to reception). It
was seamless to the users and worked pretty good.
